Jason Lewis gestures to the media as he heads towards the Meridian Line at Greenwich to officially complete his journey, making him the first to circle the globe on human power alone, 06 October 2007, in London. The 46,000-mile (74,000km) journey officially ended when he reached the point in South West London – the same place he started on 12 July 1994 with his colleague Steve Smith who decided to leave the expedition in Hawaii in 1999.

London – He was hit by a car in Colorado, attacked by a crocodile in Australia, detained as a suspected spy in Egypt and survived illness and periods of despair.

On Saturday, British adventurer Jason Lewis finally came home, completing a 13-year, 46,000-mile human-powered circumnavigation of the globe.

The 40-year-old carried his 26-foot pedal craft the last few miles up the River Thames, pushing it across the Meridian Line at Greenwich, where his expedition began in 1994.

“I’m overwhelmed,” Lewis told Sky News television after arriving. He struggled for words as he described his feelings at the close of an odyssey that took him around the globe, powered only by his arms and legs – on a bicycle, a pedal boat, a kayak and inline skates.

“It’s been my life, for 13 years, I’ve put everything into this,” he said. “To be honest I didn’t know it was going to happen. There were many times in the trip where it should have failed.”

Lewis was recruited by fellow adventurer Steve Smith, who first dreamed up the idea of going around the world using only human power in 1991. The pair had little experience at sea, but Lewis thought the prospect of hiking and biking across the world was “wildly romantic.” “The three and a half years the expedition was projected to take sounded like an acceptable amount of time to rejuvenate from the wearisome London scene without totally going AWOL,” Lewis wrote on the expedition’s website, expedition360.com.

By the time they reached America, the two adventurers had been cooped up in a broom closet-sized space for 111 days with little in the way of food, and their relationship had begun to deteriorate.

They crossed the U.S. separately, with Lewis strapping on his skates for the 3,500-mile trip to San Francisco. It was on this leg of the journey that he was hit by a car in Pueblo, breaking both legs. He spent nine months recuperating.

Smith and Lewis reunited in San Francisco and eventually pedaled from the Golden Gate Bridge to Hawaii, where the two split for good. Smith went on to write a book, “Pedaling to Hawaii,” while Lewis continued on to Australia.

He biked across the Australian Outback, dodged supertankers in the Singapore straits and hiked the Himalayas. From Mumbai, India, he pedaled his boat across the Indian Ocean to Djibouti and made his way north by bicycle through Sudan and Egypt.

While kayaking across the Barrier Reef off Australia, he was attacked by a crocodile, which bit off a piece of his paddle. He had to cycle through Tibet at night to avoid detection by Chinese roadblocks. And when he crossed into Egypt from Sudan, he was thrown in jail by the military on suspicion of being a spy.

Lewis broke the trip up into 16 legs and took breaks ranging from weeks to months.

Lewis said he hoped to raise funds for humanitarian causes and draw attention to environmental issues. He has raised $66,000.

“Instead of running away from England (as I think I was at the beginning), it is now more a question of riding forward on the back of ideas that I feel passionately about,” he wrote on his website in April.

As thousands gathered in Denver’s City Park on Monday to celebrate the life and legacy of Martin Luther King Jr., speakers didn’t mince words: King’s message was not only about love and unity, they said, but it was about fighting for freedom and equality for everyone.
